Shopify Analytics broken since 18.12.2024

Topic summary

A Shopify store running on a 1.0 theme experienced a sudden 90% drop in tracked users starting December 18, 2024, while revenue and sales metrics remained unchanged.

Missing Components:

  • Two critical cookies are not being set: _shopify_sa_t and _shopify_sa_p
  • These cookies appear correctly when testing a 2.0 theme preview

Potential Causes Identified:

  • Possible incompatibility between new Shopify analytics and 1.0 themes
  • Performance optimization scripts that may have been partially removed or are malfunctioning
  • Cookie banner configuration issues

Current Status:
The issue remains unresolved. A 2.0 theme migration is in progress but not yet complete, leaving the store needing a temporary fix for the analytics tracking problem.

Since December 18, 2024, the Shopify Analytics for one of our clients has been broken.

By “broken,” I mean that the tracked number of users has decreased by 90%, while revenue and sales have remained unchanged.

We discovered that two cookies are missing (even when everything is accepted):

_shopify_sa_t

_shopify_sa_p

The key issue is that the store is currently running on a Shopify 1.0 theme (a new 2.0 theme is in progress).

We tested the preview of a 2.0 theme, and there, we can see these two cookies.

Does anyone know if the new analytics isn’t fully compatible with the 1.0 themes?

And how to temporarily fix this?

Hello, did you hire someone to make the shop “faster”? A few scripts have been added to the shop?

If so, this is probably the reason, unfortunately we have already seen this with several customers. So if you had such a script that makes your shop faster and it either no longer works or has been removed, it was probably not all removed and a part is still there. If nobody was working on the shop and it comes by itself then it will be due to the cookie banner. The whole problem should not be due to compatibility…
